【环球时报特约记者 武彦】在近年美军卷入的多场局部冲突中，各种反导系统扮演了关键角色，但随之而来的是五角大楼武器库弹药储备告急。美国《防 务新闻》网站19日举例称，美国陆军的"萨德"反导系统拦截导弹的库存"低得令人无法接受"，可能使美军在未来的大规模冲突中"变得脆弱"。美国媒体和智 库的相关调查发现，类似情况已经成为普遍现象。 《防务新闻》网站称，以色列和伊朗今年6月爆发的12天攻防战期间，美军"萨德"反导系统消耗了近1/4的拦截导弹。"如果无法得到国会的积极干预，美军 想要补充和扩大相关库存将花费太长时间。" 来源：环球网军事 "4 年产能才能补充 12 天冲突的消耗 " 《华尔街日报》称，"标准-3"根据型号不同，采购价格大致在800万到2500万美元之间。据美国官员透露，以伊冲突中，美国海军驱逐舰向伊朗导弹发射了 约80枚"标准-3"导弹。美国《国家利益》网站描述称，美国现在每年最多生产几十枚"标准-3"导弹，但"正如在最近的行动中看到的那样，一年的产量可能几 天就打完了"。 类似的情况也出现在"标准-6"拦截导弹上。它是美国海军当前最重要的防空导弹，实际是将"标准-2"舰载防空导弹的弹体与AIM-12 ...

Core Viewpoint - The ongoing Iranian attacks are depleting Israel's missile interception inventory, prompting the U.S. to enhance Israel's defense by deploying additional missile-capable warships to the region [1] Group 1: U.S. Military Response - The U.S. has sent an additional Navy destroyer to the Eastern Mediterranean, joining three other destroyers already in the area and two in the Red Sea to form a coordinated defense posture [1] - These U.S. warships are positioned close enough to Israel to intercept missiles launched by Iran [1] Group 2: Israel's Defense Capabilities - The U.S. has replenished ground-based interceptors for the "THAAD" missile defense system previously deployed in Israel [1] - An American official indicated that if the conflict between Israel and Iran remains unresolved and Iran continues to launch missiles, Israel's advanced "Arrow-3" interception missile inventory could be exhausted in the coming weeks [1] - A researcher from Hamburg University emphasized that without the "Arrow-3," Israel would face significant challenges as interception would only be possible in the terminal phase of missile flight, greatly reducing response time [1] Group 3: Israeli Military Preparedness - The Israeli military declined to comment on the status of its air defense missile inventory but stated that it is "prepared for any situation" [1]

Core Insights - The ongoing conflict between Iran and Israel has led to significant depletion of Israel's missile defense systems, with estimates suggesting they could be exhausted in 10 to 12 days if Iran maintains its current attack intensity [1][5] - Iran's missile stockpile is also under pressure, with approximately 2,000 missiles initially available, of which around 400 have been launched, resulting in a loss of one-third of their arsenal [3][4] Group 1: Israel's Defense Situation - Israel's missile defense system is reportedly overwhelmed, leading to a "missile rationing" strategy where they must selectively intercept incoming threats [1][5] - The cost of Israel's missile defense operations is substantial, with nightly expenses reaching 1 billion shekels (approximately 285 million USD) [4] - The reliance on expensive missile systems, such as the Arrow system costing 3 million USD per missile, poses sustainability challenges for Israel's defense strategy [6] Group 2: Iran's Offensive Strategy - Iran appears to be employing a strategy of small-scale, continuous attacks to deplete Israel's defense capabilities, potentially using older and less advanced missiles [4] - The intensity of Iran's missile launches has decreased significantly, with a drop from over 150 missiles in one night to just 10 in a subsequent attack [3] - Analysts suggest that Iran's remaining missile capabilities are still significant, with more than half of their arsenal reportedly intact and possibly hidden in underground facilities [3]

Group 1 - Israel conducted large-scale airstrikes on Yemen's Hodeidah port on the 5th, resulting in dozens of casualties and destruction of port facilities and a cement factory. This action was described as retaliation for a missile attack by Houthi forces on Ben Gurion International Airport on the 4th [1][4]. - The Israeli Defense Forces (IDF) deployed approximately 20 aircraft and launched around 50 munitions, targeting Houthi-controlled infrastructure nearly 2000 kilometers away. This operation was reportedly coordinated with U.S. officials to weaken the Houthi's long-range strike capabilities [2][3]. - The airstrikes included at least 48 attacks on various facilities, with significant damage reported at Hodeidah International Airport and the Bajel cement factory, leading to 2 deaths and 42 injuries according to Houthi-controlled media [3][4]. Group 2 - The Houthi forces declared that all Israeli airports are now considered targets for their attacks, following their missile strike on Ben Gurion International Airport. This has led to several international airlines canceling flights to Israel [4]. - Israeli officials have linked the Houthi attacks to Iranian influence, with statements indicating that Israel will choose the time and place to respond to Iranian-backed actions. Iran's defense minister claimed that their new ballistic missile could evade interception by U.S. systems [4].
